Definitions
- the invention relates to a method for setting, with regard to the arm of a respective driver, an ergonomic position of a centre console, at least with a movable arm rest, and to a vehicle with such a centre console.
- Vehicles have, as a part of the dashboard, a centre console which is arranged approximately at knee height between the two front foot areas, and which extends up to the position of the arm support between the front seats or functions as an arm support itself.
- the centre console is essentially used for comfort operating and display elements, such as ventilation, air conditioning unit, car radio or navigation system, and can further comprise the gear lever and hand brake handle, depending on the type of vehicle.
- the position of the centre console is adjustable in some vehicle types.
- the movement of the centre console is coupled with that of the vehicle seat, wherein an electric motor adjusts the centre console to the position of the driver's seat, if the driver changes the position of the driver's seat.
- the positions thus achieved only cover a small portion of the positions required in reality for different inmates with different sizes and body proportions and preferences. As a result, an ergonomically optimal position is only rarely achieved.
- the prepared position must be manually post-adjusted in order to find an improved position.
- the purpose of ergonomics is to provide easy and convenient to use devices and apparatuses.
- the term "ergonomic position" refers in the present invention to a position and posture of the arm that enables an efficient and as accurate as possible operation of the operating elements (user interface components or human-machine interfaces) of the centre console, while protecting the driver (and if necessary also the front passenger) from damage to health, including longer journeys with the vehicle.
- the arm of the driver is sufficiently supported by the arm rest, which is provided by a suitable elbow position of the arm, and through an evenly optimized position of the hand, convenient operation of the operating elements (human-machine interface) in the centre console is enabled, when these lie within reach of the hand and thus in the area of the hand, without the arm having to be moved for the purpose.
- the movement, at least of the arm rest, performed with the method according to the invention can be achieved both in a horizontal movement parallel to the vehicle axis of the vehicle as well as vertically.
- the longitudinal axis of the vehicle in the direction of driving is the vehicle axis.
- the vertical direction is the direction that lies vertical to the vehicle floor (and thus also vertical to the vehicle axis).
- an ergonomic position of the arm can already be achieved through a movement along two axes that stand vertical to each other, of which one is the vertical axis.
- the movement can also be performed using suitable positioning units, along three axes that stand vertical to each other.
- the movement along the axes can be performed separately in succession or as a combined movement along several axes at the same time.
- At least of the driver In order to be able to set an ergonomic position of the arm, at least of the driver, at least the arm rest must itself be movable along the above axes.
- additional areas of the centre console can also be moved together with the arm rest, wherein the additional areas do not necessarily have to make the same movement as the arm rest.
- the automatic moving at least of the arm rest can be performed at the start of the journey or when changes are made to the vehicle interior, such as seat adjustment, steering wheel adjustment, mirror adjustment or adjustment of the headrests.
- Every unit for the movement of a component along at least two separate axes can be used as a positioning unit.
- the longitudinal movement and/or vertical movement of the arm rest can in this case be achieved e.g. via rails, rollers, cable pull, belt or sliding, wherein for this purpose, the positioning unit drives the movement e.g. hydraulically, pneumatically or electrically by means of a telescope drive, a spindle drive, an electric motor, SMA actors or in another manner.
- the positioning unit can for example be arranged in the arm rest or in other areas of the centre console and triggered accordingly with control impulses from the control unit for the execution of the desired movement.
- the optical sensors can comprise all types of sensor with which objects can be optically detected in their dimensions and positions.
- the one or more optical sensors are arranged at suitable positions in the vehicle interior for detecting the arm of the driver (and/or if necessary, of the front passenger).
- the optical sensors can be integrated in front of the driver or front passenger in the vehicle headliner (inner side of the vehicle roof), in the rear-view mirror or in the dashboard.
- the one or more optical sensors could, however, also be arranged alone or additionally in the side areas of the vehicle interior, such as in the driver's door, above the centre console or integrated in the centre console.
- the optical sensors For the optical detection of the arm, the optical sensors must in this case be arranged in such a way that, from their position, they have an at least in large parts clear view of the arm positioned on the centre console.
- the optical sensors can also be used for other purposes, such as detecting gestures to control the method according to the invention, or the vehicle equipped accordingly.
- so-called ToF cameras or a dual camera system can be used as optical sensors.
- a ToF camera or a dual camera system can be used alone or in combination with each other.
- the one or more optical sensors used in the method according to the invention or in the vehicle according to the invention are suitably connected with a control unit via data lines (wired, or wireless), so that the optical sensors can transfer sensor data to the control unit for evaluation by the control unit.
- data lines to the optical sensors can be integrated in the wire harness of the vehicle.
- the optical sensor(s) can for example be connected to the control unit via WiFi or Bluetooth or another near-field communication technology.
- the sensor data is evaluated in such a way that at least one elbow position and one hand position of the detected arm can be determined in order to be able to move the arm rest to optimize these positions relative to the operating elements on the centre console and the upper body of the driver to attain an ergonomic position of the arm automatically, without further action by the driver, and thus effectively and purposefully.
- the control unit can here be equipped with a data storage and a processor for performing the evaluation method in the form of an evaluation program. Additionally, one or more predetermined positions of the centre console or arm rest can be stored in the data storage.
- control unit is also connected at least with the positioning unit and if necessary with other components in the vehicle and in the centre console via suitable data lines (wire-supported or wireless).
- the method according to the invention enables an adjustment (movement) of the centre console with which an ergonomic position of the centre console can be easily and reliably set for any driver with any size and body proportions, in particular through the automatic adjustment, without inconvenient manual actions by the driver.
- the ergonomic position is achieved when the elbow rests on the arm support of the centre console and the hand is situated in the area of the operating elements of the centre console.
- the arm is sufficiently supported, so that no or only very slowly fatigue of the arm occurs. If the hand is situated in the area of the operating elements at the same time, these can be operated from a comfortable position of the arm without physical effort, which prevents the driver from becoming tired or being distracted from monitoring the traffic (eyes searching for the operating elements).
- the optical sensors comprise one or more ToF cameras.
- a ToF camera (or Time-of-Flight camera) is a 3D camera system that measures distances using the time of flight method.
- the cameras can comprise a PMD sensor for capturing the respective images.
- the ToF method the scene, in this case the arm in its position in the area of the centre console, is illuminated using a light pulse, wherein the camera measures the time for each image point that the light requires until it reaches the object (such as a part of the arm, a part of the arm rest or the centre console) and returns back. The required time is proportional to the distance.
- the camera thus provides the distances of the object displayed for each image point, from which the distance between certain objects can be determined.
- a ToF camera can be used at a distance range of several decimetres to several meters, and is therefore suitable for the usual dimensions in a vehicle interior. Additionally, ToF cameras offer a distance resolution of approx. 1 cm and a lateral resolution of up to 200 x 200 pixels, which is sufficient for the purpose of arm detection. The high frame rate enables fast re adjustment when moving the arm rest. With ToF cameras, the arm and certain points such as the elbow or hand can be determined sufficiently precisely and reliably for the execution of the method according to the invention.
- said evaluation method for determining the elbow position is based on sensor data from a ToF camera, said evaluation method comprises the following steps:
- the distance between the arm rest and the forearm is the respective vertical distance between the arm rest and the arm for a plurality of different points along the arm from the hand up to the end of the area of the arm above the arm rest that can be seen by the ToF camera.
- This vertical distance results from the previously determined distance of the image pixels to the ToF camera with the corresponding trigonometric evaluation.
- These distances are entered as a function of the position along the arm rest, here described as the x-coordinate. In the area of the forearm, the distance is usually small, and only fluctuates slightly along the forearm, while the distance on the other side of the elbow along the upper arm becomes continuously larger.
- the elbow is the transition point from the small slope to the large slope in distance, so that on the elbow, the largest change of the slope for this function (distance over the position or x-coordinate) emerges. Accordingly, this x-coordinate is associated with the elbow position.
- This type of evaluation is easy to perform and delivers sufficiently reliable results for moving the arm rest.
- the evaluation method for determining the hand position using the ToF camera comprises the following steps:
- the length of the forearm, including the hand follows from the previously determined distance of the image pixels for the foremost point of the hand and elbow position in relation to the ToF camera. Based on the stored data for the usual length ratios between the forearm and the hand, this can be used to precisely determine the hand position, based upon which the arm rest is moved such that the hand is then located in the area of the operating elements, so that the operating elements are then within reach of the hand without the forearm or the entire arm having to be removed from the arm rest.
- This type of evaluation is easy to perform and delivers sufficiently reliable results for moving the arm rest.
- the optical sensors comprise a dual camera system, wherein the dual camera system comprises two cameras arranged close to each other for capturing three-dimensional spatial data.
- a dual camera system relates to lenses, so that a dual camera system according to the invention can also consists of a shared housing with two lenses arranged close to each other.
- the two cameras (individual cameras or two lenses in a shared housing) enable the simultaneous capturing of the two stereoscopic fields required for the 3D images.
- the light exposure control and focus setting of both cameras or lenses are coupled.
- the two cameras or lenses are usually separated by a distance of 60-70 mm (base), which approximately corresponds to the distance between the eyes.
- Cameras or lenses for dual camera systems have sufficient depth of field and a sufficient resolution in order to reliably detect an arm in the vehicle and to be able to determine its position sufficiently precisely for the execution of the method according to the invention.
- said evaluation method comprises the following steps:
- the dual camera system is for example re-calibrated for new drivers, when the seat position is changed and/or on request, for example via a manual triggering of the calibration.
- the corresponding reference point is determined from several photographs of vehicle interior with the driver.
- the step of moving the arm rest on the centre console comprises the following steps:
- the hand is first positioned in order to then set the correct position for the elbow for this position.
- the ergonomic position can be reliably achieved and the movement can also be dynamically more easily controlled by the optical sensors, since it is only performed along one axis in each case.
- the moving of the arm rest is performed parallel to the vehicle axis in the lower vertical limit stop of the arm rest.
- limit stop refers to the end point of the possible movement of the centre console or arm rest along this axis.
- the movement in the lower limit stop prevents the arm from being over-extended during the movement along the vehicle axis as a result of a vertical position of the arm rest that may have been set too high.
- the step of moving the arm rest in the vertical direction upwards by means of a pressure sensor and a corresponding control unit is ended as soon as a contact pressure of the arm exceeds a predetermined thresholdvalue.
- the exceeding of a specified contact pressure corresponds to a too high setting of the arm rest and thus to a position of the arm that is no longer ergonomic.
- a monitoring of the contact pressure is a particularly suitable control parameter in order to prevent the arm rest from adopted a position for the arm that is no longer ergonomically optimal.
- This threshold value can for example be stored in the data storage facility of the control unit. In a preferred embodiment, the threshold value lies between 10N and 50N.
- the step of automatic moving is only performed after a predetermined minimum resting time of the forearm has been exceeded.
- This minimum resting time can in one preferred embodiment be 3 seconds, for example.
- the step of automatic moving is initiated by a certain action of the driver or another vehicle passenger comprising a gesture, an operation of a switch or a button.
- This action of the driver can for example be detected by the optical sensors and the control unit can be triggered accordingly.
- Actions such as gestures make operation easier, as no possibly small buttons must be targetedly operated, and thus the driver is less strongly distracted from monitoring the traffic.
- the thus initiated moving comprises the following steps:
- This gesture can be easily made by the driver without a loss of attention and is easily detectable by the optical sensors, so that the method according to the invention can be reliably started.
- the method is deactivatable from the vehicle interior.
- the method can simply be suppressed if it is not desired.
- a warning message is displayed or a warning tone is emitted. In this way, possible injury to the driver by the method (e.g. jamming of the arm or fingers) is prevented.
- the arm rest of the centre console is an arm rest that is divided into a first arm rest on the driver's side and a second arm rest on the front passenger's side, wherein the method is performed independently both for setting the ergonomic arm position for the driver and for the front passenger.
- the same level of convenience is available to the front passenger as to the driver.
- all the embodiments described above can also be implemented and performed for the second arm rest.
- the one or more optical sensors can also be arranged on or in the front passenger door.
- the invention further relates to a vehicle comprising a centre console with an arm rest for resting an arm of a driver and with one or more operating elements separate from the arm rest, wherein at least the arm rest is movably mounted, by means of a positioning unit, at least vertically and also parallel to a vehicle axis, one or more optical sensors for detecting the arm of the driver facing the centre console with the forearm and at least areas of the upper arm and a control unit connected to the optical sensors and the positioning unit via data lines, which is configured to perform a method according to the invention via corresponding triggering of the positioning unit.
- control unit can comprise at least one data storage and at least one processor.
- an evaluation method for determining at least one elbow position and a hand position of the arm of the driver is performed using sensor data from the sensors on the control unit.
- the control unit performs an automatic moving of the arm rest of the centre console by means of the positioning unit based on the determined elbow positions and hand positions in the vertical and horizontal direction such that after movement an ergonomic position of the arm is achieved.
- vehicle refers to all types of vehicle that have a centre console and an arm rest.
- vehicles can for example be land vehicles, water vehicles or aeroplanes.
- the vehicle according to the invention enables an adjustment (movement) of the centre console with which an ergonomic position of the centre console can be easily and reliably set for any driver with any size and body proportions.
- the optical sensors comprise one or more ToF cameras and/or one or more dual camera systems.
- At least the ToF camera and/or the dual camera system is arranged in a side door of the vehicle.
- the side door is both the driver's door and the front passenger's door.
- the side view onto the arm of the driver (or of the passenger) on the arm rest on the centre console enables a particularly precise detection of the arm and certain points such as the elbow position and hand position, and thus enables a particularly precise setting of an ergonomic position of the arm rest for the arm.
- a pressure sensor is integrated in the arm rest in order to determine whether a contact pressure of the arm exceeds a predetermined threshold value.
- the threshold value is between 10N and 50N.
- the detector can be arranged on any suitable point for the purpose in the centre console or arm rest.
- At least one of the optical sensors is configured and suitably arranged to detect certain actions of the driver or another vehicle passenger.
- the dashboard and/or the centre console or other areas in the vehicle suitable for operation are configured to deactivate the moving of the arm rest and/or to display a warning message in the vehicle or to emit a warning tone during moving of the arm rest.
- the deactivation can for example be performed by pressing a corresponding button or actuating a corresponding switch.
- the warning tone can be emitted by a suitable loudspeaker, for example via an audio system of the vehicle.
- At least the arm rest of the centre console is a two-part arm rest that is divided into a first arm rest on the driver's side and a second arm rest on the front passenger side, in order to also offer the comfort provided to the driver to the passenger, wherein the first and second arm rest can be moved independently of each other by the positioning unit and the control unit is configured to be able to set the ergonomic arm position both for the driver and for the front passenger, independently of each other.
- Fig. 1 shows a schematic drawing of an embodiment of the vehicle 1 according to the invention with movable arm rest 21 of the centre console 2 (a) in a side view and (b) in a top view.
- the centre console 2 comprises one or more operating elements 22 separate from the arm rest 21, said arm rest being movably mounted, by means of a positioning unit 3 arranged below the arm rest 21, along two separate axes (indicated by intersecting arrows) both vertically and parallel to the vehicle axis FA (see dotted axes).
- the positioning unit 3 can also be arranged in other positions in the area of the centre console 2.
- optical sensors 4 for the detection of the arm 11 of the driver 10 facing towards the centre console 2 with the forearm 11u and at least areas of the upper arm 110 are arranged on the side door Is of the driver and in the interior 1i in the centre in the dashboard 8, wherein these optical sensors 4 and the positioning unit 3 are connected via wired data lines 61 with the control unit 6, which is configured to perform the method according to the invention as displayed in Figs. 3 to 6 , in order to be able to achieve an ergonomic position of the arm through adequate setting of the position of the arm rest.
- the optical sensor 4 in the side door Is can depending on the embodiment be a ToF camera 41 and a dual camera system 42 for detecting and measuring the arm 11.
- the optical sensor 4 on the dashboard 8 can for example be provided in order to recognise gestures or other actions of the driver 10 (or other vehicle passengers) for initiating the movement of the arm rest 21. Further, here in the rear part of the arm rest 21 a pressure sensor 5 is integrated to determine whether a contact pressure AD of the arm 11 exceeds a predetermined threshold value SW, wherein the threshold valueSW is here preset in the range between 10N and 50N.
- the dashboard 8 further comprises a switch 7 via which the movement 150 of the arm rest 21 can be deactivated.

Abstract
Description
- The invention relates to a method for setting, with regard to the arm of a respective driver, an ergonomic position of a centre console, at least with a movable arm rest, and to a vehicle with such a centre console.
- Vehicles have, as a part of the dashboard, a centre console which is arranged approximately at knee height between the two front foot areas, and which extends up to the position of the arm support between the front seats or functions as an arm support itself. Here, the centre console is essentially used for comfort operating and display elements, such as ventilation, air conditioning unit, car radio or navigation system, and can further comprise the gear lever and hand brake handle, depending on the type of vehicle. For convenient operation of the respective elements, the position of the centre console is adjustable in some vehicle types.
- Currently known systems for the arrangement of the centre console in the interior of the vehicle can, however, only provide defined positions in relation to the driving mode. These positions are adjusted ex works or individually and can if necessary be approached using a so-called memory function. In one embodiment, the movement of the centre console is coupled with that of the vehicle seat, wherein an electric motor adjusts the centre console to the position of the driver's seat, if the driver changes the position of the driver's seat. However, the positions thus achieved only cover a small portion of the positions required in reality for different inmates with different sizes and body proportions and preferences. As a result, an ergonomically optimal position is only rarely achieved. Typically, the prepared position must be manually post-adjusted in order to find an improved position.
- It would therefore be desirable to have a centre console available in a vehicle with which an ergonomic position of the centre console can easily and reliably be set for any driver with any size and body proportions.
- It is therefore an object of the invention to provide a centre console in a vehicle and a corresponding method for adjusting the centre console with which an ergonomic position of the centre console can easily and reliably be set for any driver with any size and body proportions.
- This object is solved by a method for setting, with regard to the arm of a respective driver, an ergonomic position of a centre console with an arm rest and with one or more operating elements separate from the arm rest in a vehicle, wherein at least the arm rest is movably mounted, by means of a positioning unit, at least vertically as well as parallel to a vehicle axis, comprising the following steps:
- detecting an arm of the driver facing the centre console with the forearm and at least areas of the upper arm by means of one or more optical sensors;
- determining at least an elbow position and a hand position of the arm of the driver using sensor data of the sensors by means of a suitable evaluation method; and
- automatic moving of the arm rest of the centre console by means of the positioning unit based on the determined elbow positions and hand positions at least vertically as well as parallel to the vehicle axis such that, after moving, an ergonomic position of the arm is achieved.
- The purpose of ergonomics is to provide easy and convenient to use devices and apparatuses. The term "ergonomic position" refers in the present invention to a position and posture of the arm that enables an efficient and as accurate as possible operation of the operating elements (user interface components or human-machine interfaces) of the centre console, while protecting the driver (and if necessary also the front passenger) from damage to health, including longer journeys with the vehicle. In the ergonomic position, the arm of the driver is sufficiently supported by the arm rest, which is provided by a suitable elbow position of the arm, and through an evenly optimized position of the hand, convenient operation of the operating elements (human-machine interface) in the centre console is enabled, when these lie within reach of the hand and thus in the area of the hand, without the arm having to be moved for the purpose. The movement, at least of the arm rest, performed with the method according to the invention can be achieved both in a horizontal movement parallel to the vehicle axis of the vehicle as well as vertically. Here, the longitudinal axis of the vehicle in the direction of driving is the vehicle axis. The vertical direction is the direction that lies vertical to the vehicle floor (and thus also vertical to the vehicle axis). Thus, an ergonomic position of the arm can already be achieved through a movement along two axes that stand vertical to each other, of which one is the vertical axis. In other embodiments, the movement can also be performed using suitable positioning units, along three axes that stand vertical to each other. The movement along the axes can be performed separately in succession or as a combined movement along several axes at the same time. In order to be able to set an ergonomic position of the arm, at least of the driver, at least the arm rest must itself be movable along the above axes. Here, in some embodiments, however, additional areas of the centre console can also be moved together with the arm rest, wherein the additional areas do not necessarily have to make the same movement as the arm rest. The automatic moving at least of the arm rest can be performed at the start of the journey or when changes are made to the vehicle interior, such as seat adjustment, steering wheel adjustment, mirror adjustment or adjustment of the headrests.
- Every unit for the movement of a component along at least two separate axes can be used as a positioning unit. The longitudinal movement and/or vertical movement of the arm rest can in this case be achieved e.g. via rails, rollers, cable pull, belt or sliding, wherein for this purpose, the positioning unit drives the movement e.g. hydraulically, pneumatically or electrically by means of a telescope drive, a spindle drive, an electric motor, SMA actors or in another manner. The positioning unit can for example be arranged in the arm rest or in other areas of the centre console and triggered accordingly with control impulses from the control unit for the execution of the desired movement.
- The optical sensors can comprise all types of sensor with which objects can be optically detected in their dimensions and positions. The one or more optical sensors are arranged at suitable positions in the vehicle interior for detecting the arm of the driver (and/or if necessary, of the front passenger). For example, the optical sensors can be integrated in front of the driver or front passenger in the vehicle headliner (inner side of the vehicle roof), in the rear-view mirror or in the dashboard. The one or more optical sensors could, however, also be arranged alone or additionally in the side areas of the vehicle interior, such as in the driver's door, above the centre console or integrated in the centre console. For the optical detection of the arm, the optical sensors must in this case be arranged in such a way that, from their position, they have an at least in large parts clear view of the arm positioned on the centre console. In addition to detecting the arm, the optical sensors can also be used for other purposes, such as detecting gestures to control the method according to the invention, or the vehicle equipped accordingly. For example, so-called ToF cameras or a dual camera system can be used as optical sensors. Here, a ToF camera or a dual camera system can be used alone or in combination with each other. The one or more optical sensors used in the method according to the invention or in the vehicle according to the invention are suitably connected with a control unit via data lines (wired, or wireless), so that the optical sensors can transfer sensor data to the control unit for evaluation by the control unit. With a wired connection, the data lines to the optical sensors can be integrated in the wire harness of the vehicle. With a wireless connection, the optical sensor(s) can for example be connected to the control unit via WiFi or Bluetooth or another near-field communication technology. With the evaluation method, the sensor data is evaluated in such a way that at least one elbow position and one hand position of the detected arm can be determined in order to be able to move the arm rest to optimize these positions relative to the operating elements on the centre console and the upper body of the driver to attain an ergonomic position of the arm automatically, without further action by the driver, and thus effectively and purposefully. The control unit can here be equipped with a data storage and a processor for performing the evaluation method in the form of an evaluation program. Additionally, one or more predetermined positions of the centre console or arm rest can be stored in the data storage. These predetermined positions can for example be set individually for the respective driver on the basis of other measured parameters, such as the weight of the driver after sitting down in the driver's seat, in order to then move the arm rest according to the method according to the invention into an ergonomic position, on the basis of the predetermined settings for the position of the arm rest, provided this has not already been achieved by the preset position. For the further execution of the method according to the invention, the control unit is also connected at least with the positioning unit and if necessary with other components in the vehicle and in the centre console via suitable data lines (wire-supported or wireless).
- Thus, the method according to the invention enables an adjustment (movement) of the centre console with which an ergonomic position of the centre console can be easily and reliably set for any driver with any size and body proportions, in particular through the automatic adjustment, without inconvenient manual actions by the driver.
- In one embodiment, the ergonomic position is achieved when the elbow rests on the arm support of the centre console and the hand is situated in the area of the operating elements of the centre console. When the elbow is resting on the arm rest, the arm is sufficiently supported, so that no or only very slowly fatigue of the arm occurs. If the hand is situated in the area of the operating elements at the same time, these can be operated from a comfortable position of the arm without physical effort, which prevents the driver from becoming tired or being distracted from monitoring the traffic (eyes searching for the operating elements).
- In a further embodiment, the optical sensors comprise one or more ToF cameras. A ToF camera (or Time-of-Flight camera) is a 3D camera system that measures distances using the time of flight method. For this purpose, the cameras can comprise a PMD sensor for capturing the respective images. With the ToF method, the scene, in this case the arm in its position in the area of the centre console, is illuminated using a light pulse, wherein the camera measures the time for each image point that the light requires until it reaches the object (such as a part of the arm, a part of the arm rest or the centre console) and returns back. The required time is proportional to the distance. The camera thus provides the distances of the object displayed for each image point, from which the distance between certain objects can be determined. A ToF camera can be used at a distance range of several decimetres to several meters, and is therefore suitable for the usual dimensions in a vehicle interior. Additionally, ToF cameras offer a distance resolution of approx. 1 cm and a lateral resolution of up to 200 x 200 pixels, which is sufficient for the purpose of arm detection. The high frame rate enables fast re adjustment when moving the arm rest. With ToF cameras, the arm and certain points such as the elbow or hand can be determined sufficiently precisely and reliably for the execution of the method according to the invention.
- In one embodiment in which the evaluation method for determining the elbow position is based on sensor data from a ToF camera, said evaluation method comprises the following steps:
- determining a distance from the arm rest to the arm along the vehicle axis as an x-coordinate;
- detecting an x-coordinate with maximum change of slope in a function of the distance via the x-coordinate as the first x-coordinate; and
- associating the first x-coordinate with the position of the elbow.
- The distance between the arm rest and the forearm is the respective vertical distance between the arm rest and the arm for a plurality of different points along the arm from the hand up to the end of the area of the arm above the arm rest that can be seen by the ToF camera. This vertical distance results from the previously determined distance of the image pixels to the ToF camera with the corresponding trigonometric evaluation. These distances are entered as a function of the position along the arm rest, here described as the x-coordinate. In the area of the forearm, the distance is usually small, and only fluctuates slightly along the forearm, while the distance on the other side of the elbow along the upper arm becomes continuously larger. The elbow is the transition point from the small slope to the large slope in distance, so that on the elbow, the largest change of the slope for this function (distance over the position or x-coordinate) emerges. Accordingly, this x-coordinate is associated with the elbow position. This type of evaluation is easy to perform and delivers sufficiently reliable results for moving the arm rest.
- In a further embodiment, the evaluation method for determining the hand position using the ToF camera comprises the following steps:
- measuring a length at least of the forearm including the hand; and
- estimating the hand position from the measured length and a predetermined length ratio between the forearm and the hand.
- With a determined elbow position, it is thus established for the image data that the part of the arm between the hand and the elbow position corresponds to the forearm. With the corresponding trigonometric evaluation, the length of the forearm, including the hand, follows from the previously determined distance of the image pixels for the foremost point of the hand and elbow position in relation to the ToF camera. Based on the stored data for the usual length ratios between the forearm and the hand, this can be used to precisely determine the hand position, based upon which the arm rest is moved such that the hand is then located in the area of the operating elements, so that the operating elements are then within reach of the hand without the forearm or the entire arm having to be removed from the arm rest. This type of evaluation is easy to perform and delivers sufficiently reliable results for moving the arm rest.
- In a further embodiment, the optical sensors comprise a dual camera system, wherein the dual camera system comprises two cameras arranged close to each other for capturing three-dimensional spatial data.
- In this case, the term "camera" relates to lenses, so that a dual camera system according to the invention can also consists of a shared housing with two lenses arranged close to each other. When triggered, the two cameras (individual cameras or two lenses in a shared housing) enable the simultaneous capturing of the two stereoscopic fields required for the 3D images. The light exposure control and focus setting of both cameras or lenses are coupled. In order to guarantee a spatially accurate display, the two cameras or lenses are usually separated by a distance of 60-70 mm (base), which approximately corresponds to the distance between the eyes. Cameras or lenses for dual camera systems have sufficient depth of field and a sufficient resolution in order to reliably detect an arm in the vehicle and to be able to determine its position sufficiently precisely for the execution of the method according to the invention.
- In one embodiment in which the evaluation method for determining the elbow and hand position is based on sensor data from a dual camera system, said evaluation method comprises the following steps:
- capturing at least of the wrist and the elbow, preferably also the shoulder, as reference points;
- determining depth information by means of displacing the reference points in different images captured by the dual camera system; and
- calculating positions of the reference points in relation to the arm rest (21) of the centre console using a predetermined coordinate system at least as the elbow position and hand position.
- This type of evaluation is easy to perform and delivers sufficiently reliable results for moving the arm rest. As soon as the elbow is detected, the corresponding point serves as a reference point. The same applies to the wrist or other characteristic points on the body. Here, the dual camera system is for example re-calibrated for new drivers, when the seat position is changed and/or on request, for example via a manual triggering of the calibration. During calibration the corresponding reference point is determined from several photographs of vehicle interior with the driver.
- In a further embodiment, the step of moving the arm rest on the centre console comprises the following steps:
- Moving the arm rest first parallel to the vehicle axis into the corresponding position below the arm so that the hand is in the area of the operating elements when the arm rests on the arm rest; and
- then moving the arm rest in the vertical direction until the forearm rests on the arm rest.
- Through the movement initially performed along the vehicle axis, the hand is first positioned in order to then set the correct position for the elbow for this position. Through the separate movement along just one axis each, the ergonomic position can be reliably achieved and the movement can also be dynamically more easily controlled by the optical sensors, since it is only performed along one axis in each case.
- In a further embodiment, the moving of the arm rest is performed parallel to the vehicle axis in the lower vertical limit stop of the arm rest.
- In this case, the term "limit stop" refers to the end point of the possible movement of the centre console or arm rest along this axis. The movement in the lower limit stop prevents the arm from being over-extended during the movement along the vehicle axis as a result of a vertical position of the arm rest that may have been set too high.
- In a further embodiment, the step of moving the arm rest in the vertical direction upwards by means of a pressure sensor and a corresponding control unit is ended as soon as a contact pressure of the arm exceeds a predetermined thresholdvalue. The exceeding of a specified contact pressure corresponds to a too high setting of the arm rest and thus to a position of the arm that is no longer ergonomic. For this reason, a monitoring of the contact pressure is a particularly suitable control parameter in order to prevent the arm rest from adopted a position for the arm that is no longer ergonomically optimal. This threshold value can for example be stored in the data storage facility of the control unit. In a preferred embodiment, the threshold value lies between 10N and 50N.
- In a further embodiment, the step of automatic moving is only performed after a predetermined minimum resting time of the forearm has been exceeded. This minimum resting time can in one preferred embodiment be 3 seconds, for example. As a result of the minimum resting time at the start of the method according to the invention, the arm rest is prevented from immediately being moved with a random positioning of the arm on the arm rest or on the centre console, although the arm is perhaps not intended to rest on the arm rest at all. Thus, unnecessary disturbances to the driver in the vehicle interior and increased wear on the centre console and other components is avoided.
- In a further embodiment, the step of automatic moving is initiated by a certain action of the driver or another vehicle passenger comprising a gesture, an operation of a switch or a button. This action of the driver can for example be detected by the optical sensors and the control unit can be triggered accordingly. Actions such as gestures make operation easier, as no possibly small buttons must be targetedly operated, and thus the driver is less strongly distracted from monitoring the traffic.
- In a preferred embodiment, the thus initiated moving comprises the following steps:
- moving the arm rest into a lower vertical limit stop;
- holding the arm at a desired height; and
- moving the arm rest upwards in the vertical direction until the elbow rests on the arm rest.
- This gesture can be easily made by the driver without a loss of attention and is easily detectable by the optical sensors, so that the method according to the invention can be reliably started.
- In a further embodiment, the method is deactivatable from the vehicle interior. Thus, the method can simply be suppressed if it is not desired.
- In a further embodiment, during the step of moving in the vehicle, a warning message is displayed or a warning tone is emitted. In this way, possible injury to the driver by the method (e.g. jamming of the arm or fingers) is prevented.
- In a further embodiment, the arm rest of the centre console is an arm rest that is divided into a first arm rest on the driver's side and a second arm rest on the front passenger's side, wherein the method is performed independently both for setting the ergonomic arm position for the driver and for the front passenger. As a result, the same level of convenience is available to the front passenger as to the driver. Here, all the embodiments described above can also be implemented and performed for the second arm rest. In particular, the one or more optical sensors can also be arranged on or in the front passenger door.
- The invention further relates to a vehicle comprising a centre console with an arm rest for resting an arm of a driver and with one or more operating elements separate from the arm rest, wherein at least the arm rest is movably mounted, by means of a positioning unit, at least vertically and also parallel to a vehicle axis, one or more optical sensors for detecting the arm of the driver facing the centre console with the forearm and at least areas of the upper arm and a control unit connected to the optical sensors and the positioning unit via data lines, which is configured to perform a method according to the invention via corresponding triggering of the positioning unit.
- For this purpose, the control unit can comprise at least one data storage and at least one processor. In order to realize the method, an evaluation method for determining at least one elbow position and a hand position of the arm of the driver is performed using sensor data from the sensors on the control unit. The control unit performs an automatic moving of the arm rest of the centre console by means of the positioning unit based on the determined elbow positions and hand positions in the vertical and horizontal direction such that after movement an ergonomic position of the arm is achieved.
- In this case, the term "vehicle" refers to all types of vehicle that have a centre console and an arm rest. Such vehicles can for example be land vehicles, water vehicles or aeroplanes.
- Thus, the vehicle according to the invention enables an adjustment (movement) of the centre console with which an ergonomic position of the centre console can be easily and reliably set for any driver with any size and body proportions.
- In one embodiment of the vehicle, here, the optical sensors comprise one or more ToF cameras and/or one or more dual camera systems.
- In a further embodiment of the vehicle, at least the ToF camera and/or the dual camera system is arranged in a side door of the vehicle. Here, the side door is both the driver's door and the front passenger's door. The side view onto the arm of the driver (or of the passenger) on the arm rest on the centre console enables a particularly precise detection of the arm and certain points such as the elbow position and hand position, and thus enables a particularly precise setting of an ergonomic position of the arm rest for the arm.
- In a further embodiment of the vehicle, a pressure sensor is integrated in the arm rest in order to determine whether a contact pressure of the arm exceeds a predetermined threshold value. Preferably, the threshold value is between 10N and 50N. Here, the detector can be arranged on any suitable point for the purpose in the centre console or arm rest.
- In a further embodiment of the vehicle, at least one of the optical sensors is configured and suitably arranged to detect certain actions of the driver or another vehicle passenger.
- In a further embodiment of the vehicle, the dashboard and/or the centre console or other areas in the vehicle suitable for operation are configured to deactivate the moving of the arm rest and/or to display a warning message in the vehicle or to emit a warning tone during moving of the arm rest. The deactivation can for example be performed by pressing a corresponding button or actuating a corresponding switch. The warning tone can be emitted by a suitable loudspeaker, for example via an audio system of the vehicle.
- In a further embodiment of the vehicle, at least the arm rest of the centre console is a two-part arm rest that is divided into a first arm rest on the driver's side and a second arm rest on the front passenger side, in order to also offer the comfort provided to the driver to the passenger, wherein the first and second arm rest can be moved independently of each other by the positioning unit and the control unit is configured to be able to set the ergonomic arm position both for the driver and for the front passenger, independently of each other.
- The embodiments listed above can be used individually or in any combination with each other for the design of the device according to the invention and of the method.

Theoptical sensor 4 on the dashboard 8 can for example be provided in order to recognise gestures or other actions of the driver 10 (or other vehicle passengers) for initiating the movement of thearm rest 21. Further, here in the rear part of the arm rest 21 apressure sensor 5 is integrated to determine whether a contact pressure AD of thearm 11 exceeds a predetermined threshold value SW, wherein the threshold valueSW is here preset in the range between 10N and 50N. The dashboard 8 further comprises aswitch 7 via which themovement 150 of thearm rest 21 can be deactivated. Further, during the moving 150 of thearm rest 21 in the vehicle, a warning message can be displayed or a warning tone W can be emitted, for example via the audio system (not displayed explicitly) of thevehicle 1. -
Fig. 2 shows a schematic view of another embodiment of thevehicle 1 according to the invention with separately movable two-part arm rest 21 on thecentre console 2. Here, thearm rest 21 is divided into afirst arm rest 211 on the driver's side and asecond arm rest 212 on the front passenger side, wherein both arm rests 211, 212 can be moved independently of each other from arespective positioning unit 3 for therespective arm rest control unit 6 can set the ergonomic arm position ER for thedriver 10 and for thefront passenger 10b independently of each other. For all other components displayed here, reference is made to the description accompanyingFigure 1 . -
Fig. 3 shows a schematic view of an embodiment of themethod 100 according to the invention for setting an arm-related ergonomic position of acentre console 2 with an automaticallymovable arm rest 21 and with one ormore operating elements 22 separate from thearm rest 21 in avehicle 1, wherein thearm rest 21 is movably mounted by means of apositioning unit 3 vertical as well as parallel to a vehicle axis FA. Themethod 100 according to the invention here comprises the steps of detecting 110 anarm 11 of thedriver 10 facing the centre console with theforearm 11u and at least areas of theupper arm 110 by means of one or moreoptical sensors 4; determining 120 at least an elbow position EP and a hand position HP of thearm 11 of thedriver 10 using sensor data SD of thesensors 4 by means of asuitable evaluation method 130; and automatic moving 150 of thearm rest 21 of thecentre console 2 by means of thepositioning unit 3 based on the determined elbow positions EP and hand positions HP at least vertical as well as parallel to the vehicle axis FA such that after moving 140 an ergonomic position ER of thearm 11 is achieved, where the elbow 11e rests on thearm rest 21 of thecentre console 2 and thehand 11h is in the area of theoperating elements 22 of thecentre console 2. The step of moving 150 thearm rest 21 can here be performed as amovement 150 along two separate axes in succession, wherein first, a moving 152 of thearm rest 21 parallel to the vehicle axis FA into the corresponding position below the arm 11 (so that thehand 11h is located in the area of theoperating elements 22 when thearm 11 is resting on the arm rest 21) and then 154 in the vertical direction VR (until theforearm 11u rests on the arm rest 21) is performed. Here, thearm rest 21 can be moved in the lower vertical limit stop of thearm rest 21 along the vehicle axis. Here, the step of automatic moving 150 can only be performed after a predetermined minimum resting time MVD of theforearm 11u on thearm rest 21 has been exceeded. If thearm 11 remains on thearm rest 21 for less than the minimum resting time MVD, thearm 11 continues to be recognised by theoptical sensors 4, although without amovement 150 of thearm rest 21 being performed. In order to avoid exceeding an optimal height of thearm rest 21, the moving 150 of thearm rest 21 in the vertical direction VR upwards by means of apressure sensor 5 and acorresponding control unit 6 is endedas soon as a contact pressure AD of thearm 11 exceeds a predetermined threshold value SW. If this threshold value SW has not yet been exceeded and the ergonomic position of thearm 11 has not yet been reached, thevertical movement 150 of thearm rest 21 is continued upwards. Here, during moving 150 in thevehicle 1, a warning message can be displayed or a warning tone W can be emitted. Themethod 100 can be deactivated from the vehicle interior 1i. -
Fig. 4 shows a schematic view of two embodiments of themethod 100 according to the invention withdifferent evaluation methods 130 for determining elbow and hand positions EP, HP, where in the left branch theoptical sensor 4 is a ToF camera 41 and in the right branch the optical sensor is adual camera system 42. Accordingly, therespective evaluation methods 130 used differ. The evaluation method with the ToF camera 41 comprises the steps of determining 132 a distance D1 from thearm rest 21 to thearm 11 along the vehicle axis FA as an x-coordinate; the detecting 134 of an x-coordinate XE with maximum change of slope in a function of the distance D1 over the x-coordinate as first x-coordinate XE; and the associating 136 of the first x-coordinate X1 with the position of the elbow EP. Thus, the elbow position EP is determined here. The method further comprises the step of measuring 138 a length L at least of theforearm 11u including thehand 11h and the estimating 140 of the hand position HP from the measured length L and a length ratio between theforearm 11u and thehand 11h stored in the data storage of thecontrol unit 6. Thus, the hand position is also determined, according to which the step of moving 150 can be performed. The alternative evaluation method to this, with adual camera system 42, comprises the steps of capturing 142 at least thewrist 11g and the elbow 11e, preferably also the shoulder, as reference points; the determining 144 of a depth information by moving the reference points captured in different images by thedual camera system 42; and the calculating 146 of positions of the reference points in relation to thearm rest 21 on thecentre console 2 using a predetermined coordinate system, at least as the elbow position EP and the hand position HP. Thus, the elbow and hand position EP, HP is also determined, according to which the step of moving 150 can be performed. -
Fig. 5 shows an example for the distance D1 of thearm 11 in relation to thearm rest 21 as a function of the x-coordinate in the direction of the vehicle axis FA for determining the elbow position EP by means of a ToF camera 41. The distance D1 between thearm rest 21 and theforearm 11u is the respective vertical distance between thearm rest 21 and thearm 11 for a plurality of different points along thearm 11 from thehand 11h up to the end of the area of thearm 11 above thearm rest 21 that can be seen by the ToF camera 41. These distances D1 are entered as a function of the position along thearm rest 21, here described as the x-coordinate. In the area of theforearm 11u, the distance D1 is usually small, and only fluctuates slightly along theforearm 11u, while the distance D1 on the other side of the elbow 11e along the upper arm 11o becomes continuously larger. The elbow 11e is the transition point from the small slope to a large slope in the distance D1 over the x-coordinate, so that on the elbow 11e, the largest change of the slope for this function emerges. Accordingly, this x-coordinate XE is associated with the elbow position EP. This type of evaluation is easy to perform and delivers sufficiently reliable results for moving thearm rest 21. The distance from the elbow EP, XE at the start of the arm is determined as the length L, from which the precise hand position is determined according to a predetermined forearm-hand ratio. Here, the start of the arm always lies in the direction of the dashboard and is thus not interchangeable with the opposite end of the arm. -
Fig. 6 shows a schematic view of an embodiment of themethod 100 according to the invention, said embodiment having action-controlled initiation of the automatic moving 150 of the arm rest, wherein initiation occurs through a specific action AK of thedriver 10 or anothervehicle passenger 10b, for example a gesture or an operation of a switch or a button. In the case of activation via a gesture, themethod 100 can comprise the following steps of moving 160 thearm rest 21 into a lower vertical limit stop; holding 162 thearm 11 at a desired height; and moving 164 thearm rest 21 in the vertical direction VR upwards, until the elbow 11e rests on thearm rest 21. - The embodiments displayed here are only examples for the present invention and should therefore not be regarded as being exhaustive. Alternative embodiments considered by a person skilled in the art are equally covered by the area of protection of the present invention.
